Abstract: A film formation system and a film formation method are disclosed. The film formation method includes the following steps performed in the film formation system that includes a container containing liquid, a liquid draining device for draining the liquid, a ring-shaped component installed in the container, and a carrying component installed in the liquid in the container for carrying at least a substrate: enabling the carrying component in the liquid and enabling the ring-shaped component to float on the liquid; when a film layer that is composed of nano-spheres is formed on the liquid, locating the film layer in a ring of the ring-shaped component; and removing the liquid, allowing the film layer to move downward in accordance with the ring-shaped component and be formed on the substrate, thereby preventing the nano-spheres from contacting an inner wall of the container and bursting, through the installation of the ring-shaped component.

Abstract: A light-emitting device includes a photonic crystal layer formed above a light-emitting chip and covered with a phosphor layer for diffusing light emitted from the light-emitting chip. The diffused light further excites the phosphor layer to emit colored light of multiple colors. The multiple colors are then mixed to generate white light.
